DX Toolbox

iPhone /iPad Shortwave Radio Propagation App

DX Toolbox helps you forecast shortwave radio propagation conditions. It features several propagation forecasting tools, allowing you to quickly and easily estimate current HF (Shortwave) propagation conditions between any two locations in the world, and is ideal for the ham radio operator, shortwave listener, or other radio enthusiast.

Radio propagation conditions can also be estimated between any two points on the Earth. Graphs of these conditions can be generated for a given frequency or time, and MUF/LUF graphs can also be displayed.

A grayline map of the world is also available. Radio propagation between locations within the grayline region of the world is often greatly enhanced. DX Toolbox's grayline map makes it easy for you to determine where those locations are. Grayline propagation has been used by expert radio operators and DXers for years to catch elusive stations. A plot the great circle (both short and long) path between your location and another station is also displayed, as well as the beam heading and distance. The location of the currently transmitting NCDXF/IARU beacon can be displayed on the map as well.

DX Toolbox displays the following important solar and geomagnetic readings:
